BOOK-COVER PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 622,178, dated March 28, 1899.

Application filed May 10, 1898. Serial No. 680,753.

To aZZ whom it may concern.-

Be it known that I, GEORGE CORNWALL, a citizen of the United States, residing at Port Chester, in the county of Westchester and 5 State of New York, have invented certain new and useful Improvements in Book-Cover Protectors, of which the following is a specification.

The object of my invention is to provide an improved book-cover protector which will be applicable for covering books of various sizes.

To this end my invention consists of a bookcover protector comprising a central backingsheet of approximately square shape adapted to be placed upon the book-back with one of its diagonals extending along the central back line of the book and four corner pocket-pieces adapted to inclose the corners of the bookback and be secured to the backing-sheet at their meeting edges.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a perspective view of an open book, showing portions of my book-cover protector api 5 plied thereto, this view being for the purpose of showing the manner of applying the cover protector to the book. Fig. 2 is a plan view of the book-cover protector detached from the book and looking at the inside. Fig. 3 is a 0 plan View of the central backing-sheet of the cover-protector. Fig. 4 is a plan view, partly broken away, of one of the corner pocketpieces. Fig. 5 is a detail perspective View of the same. Fig. 6 is a plan view representing 3 5 the central backing-sheet in position against the back of the book and the four corner pocket-pieces detached therefrom. In this figure the application of the central backingsheet to the book is slightly diiferent from the preferred form illustrated in'Figs. 1 and 2.

Fig. 7 is a plan view of the closed book having my cover-protector applied. Fig. 8 is a plan view of a blank sheet, illustrating the manner of cutting and folding the blanks for forming the corner pocket-pieces. Fig. 9 is a plan view of a partially-completed corner" pocket-piece. Fig. 10 is a similar View of the completed corner pocket-pieces.

My improved book cover protector com- (No model.)

prises a central backing-piece 1 of approximately square shape and corner pocket-pieces or envelops 10, the backing-piece being adapted to be applied to the back of the book with one of its diagonals extending along the central line of the back of the book and the corner pocket-pieces or envelops being adapted to fit over the corners of the book-cover and be secured to the adjacent edges of the backing-sheet.

Referring to Figs. 1 and 2, it will be observed that the backing-sheet 1 has the longitudinal corner portions 2 3 bent inwardly under the sheet and next to the back of the book 15, the diagonal of the backing-sheet extendin g along the central line of the back of the book. The corner-pieces 2 3 are bent over sufiiciently far to make the length of the backing-piece the proper length for the back of the book. It is then preferred to cut off one of the transversely-projecting corners, such as 4, to form astraight edge at one side to come even with one side of the book-back 15. The opposite transversely-projecting corner 5 of the backing-strip 1 extends to the outer edge of the opposite side 15 of the book-cover. One of the corner pocket-pieces 10 is then placed over a corner of the side 15 of the book-back and secured to the central backing-piece 1. Then the opposite corner-piece 10 is placed over the opposite corner of the side 15 of the bookback, the pocket piece being fitted snugly against the edge of the book-back and the straight edge 4: of the backing-sheet formed by cutting 06 the corner 4. Fig. 1 shows these parts as far as described, with the exception of the second corner pocket-piece. With the two corner pocket-pieces and backing-sheet applied as just described, the corner 5 of the backing-sheet 1 is bent around the edge of the side 15 of the back of the book and held securely in its place, while the remaining two corner pocket-pieces 10 are applied to the corners of the side 15 and secured in place upon the backing-sheet 1. The position of the several parts of the book-cover protector in its preferred form is shown in Fig. 2 with the book removed.

The application of the cover-protector just described With reference to Figs. 1 and 2 is the preferred application of my invention but should the central backingsheetl betoo small to allow for the cutting off and bend;-

ing over of the transverse. corners the central backing-piece may be applied to the book as shown in Fig. 6, the corner pocket-pieces overlap 'iingthe centralbacking-sheet sufliciently to make a serviceable cover. i In the form shown in Fig. 6 it will be observed that the longitudinally-extending corners of the precentral sheet are bent under, asinthe ferred form. 1 1 1 1 1 Referringto Figs. 8, 9, and 10, it will be observed that the preferred method of mak-1 ing the corner pocket-pieces is by taking a square sheet andseveringit into four equal triangular parts a Z) c'd'by cutting it along its diagonal lines. Each of these pieces then has a stripe (indicated by dotted lines) cut away from it and is'folded centrally upon the line i f. (Alsoindicatedbydottedlines.) The projecting strip 9 is then proiddedwith mucilage or otheradhesive substance and is b ent over alongthe line g and securely fastened to the body of the corner pocket-piece. 1 'lheseveral steps describedin the manufacture of the corner pocket-pieces are illustratedin Figs.- 8 9,

I andlOV The'eornersofthecompletedpocket or envelop are then cutoff and rounded to givetheni a more finished appearance: A-

strip of adhesive materialhis also applied to the inner face ofoneside of each of the en- 'velopsor corner pocket-pieces. 1

g It will be observed thatmyiinproved book The cover-protector may be ornamented with any suitable designs and may have any desired printed matter applied to it to designate the book which it contains.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, isy y ,7 1 1 1.
